I was suggested making a journal of my octopus, so here we go! I'm getting my first octopus in about 2 months as I just got my aquarium up and running. The species isn't confirmed yet, but there is a high chance it'll be a vulgaris (and if it is a vulgaris, it's most likely from Bali according to my LFS). Anyways, this will be a pre-octopus post so not really much interesting. Gonna leave a few pics of my aquarium system.

Got myself 3 cleaner shirmps, 3 fire shrimp, 1 hermit crab that ate 2 of my snails, now only 4 snails, 2 clownfish as well as an imperator fish

The back and the overflow

Using this neat little box here as overflow. I will have to cut the top of my aquarium to fit it in because right now the lid is laying on top of it. I'm aware that I also need to build caves for him, but I'll get to that later on. The only 2 pipes that take in water is the circulation pump to the left on the first pic, but the holes on it are so small that I'm not gonna worry about it unless I see it starting to chop up my octopus. The other one is the overflow where I've put a sponge, but will have to "lock" it there so Arthur doesn't rip it out and go down to the sump. Also the lid will obviously have to be secured, but thats alright, I can fix that. The only thing I'm not sure how to fix is the fluorescents as they would be on the inside of the aquarium. Will this be problem?

Welcome Reggie! One thing I don't see in your set up is a skimmer in the sump. I highly recommend adding one. There are tons of discussions about skimmers and how much you need to spend on them but for ceph ink, it is important to at least have one and good low end models work for me.

If your animal comes from Indonesia, it will most likely be in the Abdopus family (ie not a vulgaris). We see two complexes coming from their, one is the Adopus (often the much enjoyed diurnal aculeatus) and the other Macropus (a nocturnal group). I have captured a few links to discussions for new keepers here and the Species topic should be of interest. I also recommend reading all the stickied posts in the octopus care forum to better understand what to expect.

Looking forward to your progress!

Okay, thank you for the tips. Actually if you look at the 2nd picture you can see the skimmer to the right there, hanging on the outside of the sump :)

Hi Reggie welcome how big is ur tank and if your octopus is anything like mine you won't have any shrimp or crabs left lol and the fish may make your octopus hide more than normal or even pick at it other than that good luck they are so much fun to interact with.

Thanks for mentioning the clown Inkman, I saw it and forgot to comment. My standing recommendation is NO FISH or any kind with an octopus. Often people cycle with damsels and accept the thought that the octopus will eat it (they are particularly hard to catch). I always recommend all fish be removed before adding an octopus. They will pester an octopus looking for food, sometimes attacking it, resulting, as Inkman noted, limiting the time it is out of its cave. All cephs are susceptible to stress ailments that effect their health and physical attacks can lead to infections that don't heal easily.

SOME shrimp survive an octopus but few. There is no harm to the octopus to leave them in the tank.

The new keeper's discussion links post I linked above includes proven tankmates along with some that are strongly not recommended.

Hey Inkman, thanks :) The tank is 450l. I'm aware that the shrimp and crab will be eaten, but didn't know the fish could be picking on him. Actually I thought he would just eat everything live in there. I guess I'll remove the fish before he comes in then.

EDIT: Sorry, it's 240l

Arthur may eat fish but in my opinion its not worth the chance its hard enough just to get to house and aclimated without overstressing to them

63 gallons (240 liters) is a good sized tank for all the animals we typically see available in the US. Vulgaris needs (usually) a larger tank. The US vulgaris is smaller than the Mediterranean animal but still needs a tank in excess of 130 gallons (~500 liters). This would be small for a Mediterranean animal and 300 gallons has been suggested as the minimum size (~1135 liters) but we have no recorded experience with them. As I mentioned, in the US it is rare to see vulgaris in the hobby trade and we have no recorded vulgaris from Indonesia so hopefully, Arthur will be Abdopus aculeatus.

You can offer dead fish as a food item (not suggesting that you kill the clown for this purpose). Almost anything from the ocean that the animal will accept can be considered a food item. Their primary needs are met with crab (live preferable but disable any claws) and shrimp - fish should be a supplementary but not primary item. Human seafood items are usually readily accepted and can be thawed frozen foods.

I see. So if it is really from Indonesia, it's not a vulgaris at all? Also I have the impression that most Indonesian octopuses don't get very big, isn't that so? Oh, and could you recommend any books on cephalopods? Caring/encyclopedias/study books?

If you read my "box of chocolates" post you should be getting the idea that the people who provide octopuses for sale (the entire chain - the people that catch them, the people that import them and the local vendors) have little knowledge of octopus species. As hobbyists we need to accept this, especially knowing that the experts often have difficulty identifying many species, particularly from photos or short exposure.

O. vulgaris (as a complex, there are local differences) are the most common species and are found world wide, typically in colder water than a typical warm water aquarium (we do have a Caribbean variety in the US that is smaller but is not as common as our Common Caribbean Octopus - O. briareus - that looks nothing at all like a vulgaris :roll:. It will sometimes be tagged that way because of its common name). However, the use of the name is often a mislabeling. Its common name is, common octopus. This naming often tags the most common octopus in an area as vulgaris, regardless of the actual species. In Indonesia, a common animal is aculeatus (or at least one of the animals in the Abdopus complex). Aculeatus is not a large animal and will be well suited for your tank. The second most common we see imported from this area is nocturnal and in the Macropus complex. It is also well suited for your tank so you should be OK with anything coming from that area. The is likely little difference between the US and Norway as to what is imported from the region but it will be interesting to see which piece of chocolate shows up :biggrin2:

Note: In case my "box of chocolates" reference does not make sense
I assume that everyone, regardless of country, is familiar with boxes of chocolate coated candy with varying contents inside the chocolate covering. The reference comes from no knowing what kind of filling you get until you bite into it.
